    What are you having trouble to understand?
    I think it will be good for you if you could tell us your problem then we'll try to explain rather than telling you the answer right away.

    I know how to do the equation, but I don't understand how I can turn that into a graph.

    F represents the y axis.. the other side of the equal sign will represent the X result..

    For every value of C, there will be a value for F..

    Plot C vs F and you get your graph.

    Looks like:

    Should be the reverse of that though.. because your plotting Celsius on the X axis instead of the Y axis like the graph above..

    5F = 9C + 32*5

    5F - 160 = 9C
    C = (5F - 160)/5
    C = F - 32
    Set C to 0...
    0 = F - 32
    When F = 32, C will be 0.. when F < 32 C will be less than 32..

    Thanks that helped. The only thing now that I'm not sure about is question 3.

    5F - 160 = 9C
    C = (5F - 160)/5

    You divided one side by 5 and the other by 9 :P

    And it could be done easier:
    F = 9 * c / 5 + 32
    c = 0
    F = 9 * 0 / 5 + 32
    F = 32
